Abstract

A bicycle handlebar clock mounting structure installed onto the bar member comprising various different model handlebars. The clock mount is an inverted U-shaped construct and, furthermore, an end section extends inward from each of its two lateral extremities, an elongated adjustment hole is formed in each of the two end sections, and the center portion of the clock mount is of a regular tubular profile. A recessed arcuate surface fabricated along the underside of the clock enables sturdy positioning against the center portion of the clock mount. After screws are inserted through the adjustment holes in the end sections of the clock mount, the screws are tightened to attach various shape handlebars to the bicycle by means of clamp cover at the front end of the stem, enabling the clock mount to be widely utilized on a range of various style handlebars and thereby achieving clock installation practicality and convenience.

Description

BACKGROUND OF THE INVENTION
• 1) Field of the Invention
• The invention herein relates to bicycle accessories, specifically a bicycle handlebar clock mounting structure that provides for clock installation on various model handlebars and thereby achieves installation practicality and convenience.
• 2) Description of the Prior Art
• In the conventional installation of clocks on bicycle handlebars, since a recessed arcuate surface is typically fabricated along the underside the said clock, a double-sided adhesive plastic tape affixes it to the surface of the handlebar bar member. However, as the recessed arcuate surface under the clock only provides for attachment to handlebars having a regular tubular profile and existing handlebars are not only available in such consistent tubular profiles, when fitted on current designs of differently shaped handlebars, as indicated inFIG. 1-A andFIG. 1-B, the clock A cannot be fully mounted onto the surface of the said irregular tubular profile handlebar B such that when a bicycle so equipped travels over rough roads, the said clock A readily falls off due to insufficient surface area adhesion during continuous vibration.
• In view of the said situation, the applicant of the invention herein sought improvements to address the said shortcomings that culminated in the successful development of the present invention which is submitted in application for patent rights.
SUMMARY OF THE INVENTION
• The primary objective of the invention herein is to provide a bicycle handlebar clock mounting structure that is installed onto the bar member comprising various different model handlebars in which the clock mount is an inverted U-shaped construct and, furthermore, an end section extends inward from each of its two lateral extremities, an elongated adjustment hole is formed in each of the two end sections, and the center portion of the clock mount is of a regular tubular profile; a recessed arcuate surface is fabricated along the underside of the clock enables sturdy placement against the center portion of the clock mount; after screws are inserted through the adjustment holes in the end sections of the clock mount, the screws are tightened to attach various shape handlebars to the bicycle by means of clamp cover at the front end of the stem, enabling the clock mount to be widely utilized on a range of various bend handlebars and thereby achieving clock installation practicality and convenience.

DETAILED DESCRIPTION OF THE INVENTION
• Referring toFIG. 2 andFIG. 3, the bicycle handlebar clock mounting structure of the invention herein is installed onto the anterior aspect of the bar member comprising variousdifferent model handlebars2, theclock mount3 is an inverted U-shaped construct and, furthermore, anend section31 extends inward from each of its two lateral extremities, anelongated adjustment hole32 is formed in each of the twoend sections31 and, furthermore, the center portion of theclock mount3 is of a regulartubular profile33; and a recessedarcuate surface41 is fabricated along the underside of theclock4.
• As such, when preparing to assemble various differentstyle bend handlebars2 and2′ (as shown inFIG. 3 andFIG. 5) between thebicycle1stem11 and clamp cover12 (as shown inFIG. 4-A andFIG. 4-B), after thescrews13 for fastening together thestem11 and theclamp cover12 are first inserted through121 holes of theclamp cover12 as well as theadjustment holes32 in the twoend sections31 of theclock mount3, they are then tightened in the threadedholes111 of thestem11, thereby attachinghandlebars2 and2′ of various shapes to thebicycle1, while firmly positioning theclock mount3, thereby reducing screw count and not affecting structural strength, following which the recessedarcuate surface41 fabricated along the underside of theclock4 is sturdily positioned against thetubular profile33 surface at the center portion of theclock mount3.
• As a result, since the clock-4 is positively secured against theclock mount3, theclock mount3 is not affected by differentstyle bend handlebars2 and2′, and is fully screw fastened to the bicycle frame, the saidclock4 is not dislodged by vibration when the host bicycle travels over rough roads.
• In summation of the foregoing section, since the installation of theclock mount4 of the invention herein is unaffected by dissimilarities among various different styles and shapes of handlebars, the present invention achieves installation practicality and convenience; as such, the invention herein has demonstrable utility and complies with the application requirements in Article 47 of the New Patent Law, the present invention is lawfully submitted to the patent bureau for review and the granting of the commensurate patent rights.

Claims (1)

1. A bicycle handlebar clock mounting structure that is installed onto the anterior aspect of the bar member comprising various different model handlebars in which the clock mount is an inverted u-shaped construct and, furthermore, an end section extends inward from each of its two lateral extremities, an elongated adjustment hole is formed in each of the two said end sections and, furthermore, the center portion of the said clock mount is of a regular tubular profile; as such, when preparing to assemble various different style bend handlebar between the bicycle stem and clamp cover, after the screws for fastening together the said stem and the said clamp cover are first inserted through holes of the said clamp cover as well as the said adjustment holes in the said two end sections of the said clock mount and then tightened in the threaded holes of the said stem, a recessed arcuate surface fashioned along the underside of the clock is sturdily positioned against the said tubular profile surface at the center portion of the said clock mount and thus the clock mount can be widely utilized on a range of various shaped said handlebars, thereby achieving clock installation practicality and convenience.
